Question

You don't have to show your work i just need to compare the answers you get with the answers that i got to see if i'm right.

28. Angular velocity and linear velocity have the same dimensions. l his statement is A. True B. False 29. A solid sphere and a hollow sphere roll down an incline. Assume both objects start from rest from the same initial height above ground. The hollow sphere is slower than the solid sphere A. mass of the hollow sphere equals the mass of the solid sphere B. radius of the hollow sphere equals the radius of the solid sphere C. both masses and radii are equal D. the hollow sphere is always slower regardless of their ma and rad 30. Suppose the objects in the problem above have the same mass and radius Which object has more kinetic energy when it reaches the bottom of the ncline? A. The solid sphere B. The hollow sphere C. They both have the same kinetic energy D. More information is needed 31. Suppose a solid sphere and a hoop are rolled up an incline plane with the same initial velocity. Which object will travel furthest up the plane? A. The solid spher B. The hoop C. The maximum heights will be the same since the the same r initial velocities are 33. Two objects of the same volume are placed in water. Object A floats and Object B sinks. The greater buoyant force is on A. object A B. object B C. both are same 34. Two objects of the same mass are placed in water. Object A floats and Object B sinks. The greater buoyant force is on A. object A B. object B C. both are same 35. If gauge pressure is tripled, the absolute pressure will A. not change B. be reduced by a factor of 3 C. triple D. not enough information is given to determine what happens 36. You wear snowshoes in the snow because snowshoes help reduce the against the snow A force B. pressure C. mass 7. When submerged under water, the apparent mass o cubic meter of pure gold is 18300 kg.
